<p>
        The API of <code class="code">Zend_Currency</code> has changed in the past to increase
        the usability. If you started using <code class="code">Zend_Currency</code> with a
        version which is mentioned in this chapter follow the guidelines below
        to migrate your scripts to the new API.
    </p>

<p>
            Creating an object of <code class="code">Zend_Currency</code> has become simpler.
            You now do not longer have to give a script or set it to null. The optional
            script parameter is now an option which can be set through the
            <code class="code">setFormat()</code> method.
        </p>
<pre class="programlisting">&lt;?php
$currency = new Zend_Currency($currency, $locale);
        </pre>
<p>
            The <code class="code">setFormat()</code> method takes now an array of options which
            can be set. These options are set permanent and override all previous
            set values. Also a new option 'precision' has been integrated. The
            following options has been integrated:

            </p>
<div class="itemizedlist"><ul type="opencircle"><li style="list-style-type: circle">
<p>
                        <span class="strong"><strong>position</strong></span>:
                        Replacement for the old 'rules' parameter.
                    </p>
<p>
                        <span class="strong"><strong>script</strong></span>:
                        Replacement for the old 'script' parameter.
                    </p>
<p>
                        <span class="strong"><strong>format</strong></span>:
                        Replacement for the old 'locale' parameter which does not
                        set new currencies but only the number format.
                    </p>
<p>
                        <span class="strong"><strong>display</strong></span>:
                        Replacement for the old 'rules' parameter.
                    </p>
<p>
                        <span class="strong"><strong>precision</strong></span>:
                        New parameter.
                    </p>
<p>
                        <span class="strong"><strong>name</strong></span>:
                        Replacement for the ole 'rules' parameter. Sets the full
                        currencies name.
                    </p>
<p>
                        <span class="strong"><strong>currency</strong></span>:
                        New parameter.
                    </p>
<p>
                        <span class="strong"><strong>symbol</strong></span>:
                        New parameter.
                    </p>
</li></ul></div>
<p>

        </p>
<pre class="programlisting">&lt;?php
$currency-&gt;setFormat(array $options);
        </pre>
<p>
            The <code class="code">toCurrency()</code> method does no longer support the optional
            'script' and 'locale' parameters. Instead it takes an options array which
            can contain the same keys as for the <code class="code">setFormat</code> method. 
        </p>
<pre class="programlisting">&lt;?php
$currency-&gt;toCurrency($value, array $options);
        </pre>
<p>
            The methods <code class="code">getSymbol()</code>, <code class="code">getShortName()</code>,
            <code class="code">getName()</code>, <code class="code">getRegionList()</code> and
            <code class="code">getCurrencyList()</code> are no longer static and can be called
            from within the object. They return the set values of the object if no
            parameter has been set.
